(Mexico) (nothing labeled) Some large and good examples of copper ore - a breccia - from the Monteguma Copper Co. + large specimens and 4 bottles of crushed mat. In another case: 1 page or piece, 9 melted pieces and 4 bottles of reduced material. Much argentiforous material but as nothing is labeled one cannot say what is wanted. (Instituto Geologico Nacional) Geological Survey not yet installed. Has a general collection of rocks and minerals. "Cananea Consolidated Copper Co" "C.A." has a good exhibit of copper ores and some samples of copper, as gathered from the native copper sheets are desirable (from 3 feet square by ? inch thick. Consolidated (?) electric fans). Rather rather very desirable although some of the material may be deserted. But look here, The entire Mexican exhibit is in com- plete and adequately exhibited. Eduardo Martinez Baca chief of Mexico Mine Metallurgy Dep., will let us have material. See card J Baca.
